Greetings to my fellow home energy professionals...
I have been thinking about ways to work on one's garage to make it energy efficient and ways to use the space for more than just resting a car and storage items.
Garage Doors for instance qualify for Home Owner Tax Credits - Ref: http://www.run-local-garage-door.com/energy-tax-credits/
So there could be more ways to add to these tax credits and increase energy efficiency. Perhaps, installing a localized solar device on garage roof or energy efficient (biological) lightning inside the garage
Would you like to share your thoughts on ways to make a garage more useful in decreasing one's energy footprint.
Hi again Brian,
If you have any questions on the roll uo insulared doors at the military base, the man in Marylad that supervised that project is a member of this website.
Feel free to contact him also if you have any questions on that particular project. Gene is really busy right now but he will get back to you as soon as he can. Those two doors were coated just last Saturday with more applications to follow.
I agree with venting the garage. Just not with a solar powered attic fan.
Hal, I would be careful with your energy saving performance claims of radiant barrier paint as Iam sure you know all too well. The only problem I have with above is "problem solved", not really a performance claim but highly questionable considering some of the surfaces in the pics are getting very little direct sunlight at all.
Are you saying that your coating applied to the door of an overheated garage will solve its overheating issues?
Hi again Brian. I know exactly what you are saying. Unfortunately for our industry, there has been a lot of bad products for many years that do not live up to their claims. That has given our industy a huge black eye, lot of snake oils out there.
Very cloudy day when the military base pictures were taken. They got 2" of rain that weekend, ergo the plastic protecting our coating.
As an example; the doors in the bottom picture at the beer plant in Vegas. The doors would reach a temp of well over 200 degrees. Applied our coating and it then had a surface temp of 112 degrees on a 108 degree day. Very heavy gauge metal doors there.
Our coating brings the ouside srface temp down to within 5 degrees of whatever the ambient air temperature is at the time. There are also many cases on our website to demonstrate how much heat it will retain when it is colder outside than it is inside the structure.
I am adding a statement from a software engineer that got some of our coating and did several applications at his home. One of those was to the inside of his garage door to keep out heat.
The major problem with trying to use a garage for multiple uses, especially in our northern climates, is controlling that indoor environment. The garage will need heating if used for doing work in there in the colder periods of the year. Heating efficiently requires insulation and ventilation (as well as lighting and maybe water, etc.). Bringing a car into the multi-use garage requires lots of short term ventilation, if it is to then be used as a work area. In the winter, the car will be bringing in lots of snow, which will melt and put a lot of moisture in the air. Even when above freezing, the car would bring in lots of water when it has been raining.
That is a lot of conflicting requirements to meet, which would be very difficult to accomplish in a reasonably "efficient" manner. Moisture in a space that encounters large swings in temperature is probably the most difficult problem to solve efficiently. ("It is all about the Dew Point")
